It is a soft IP core, which provides high-bandwidth direct memory access between memory and AXI4-Stream video type target peripherals including peripherals which support AXI4-Stream Video Protocol. The core provides efficient two dimensional DMA operations with independent asynchronous read and write channel operation. For more information on the IP, please refer to http://www.xilinx.com/support/documentation/ip_documentation/axi_vdma/v6_1/pg020_axi_vdma.pdf Use cases: ++++++++++ 1.
